Look at your meeting as a fact finding mission, there really is to nothing fear, you are only attempting to make an informed decision. The attorney will interpet the law for you, you will make the business decisions pertaining to your life and in 99% of the cases that will not be done on the spot. Family Law Attorneys understand all the emotions that you are going thru, so they are not anticipating an instant response, nor do they want one
It will be fine, state the facts as you see them, have an overview of your financial situation, ask any questions that you may have...and....relax.
